NeSSI: A Shared VisionR&D, End Users, Suppliers
❚ An industrial platform for “lab on a chip” sensors
❚ a suite of physical and chemical sensors and standard “off the shelf” software
❚ at the pipe - “analytical transmitter”❚ highly reliable - low maintenance❚ lower LTCO and capital costs❚ profitability for suppliers

Summary
❚ NeSSI/CPAC has articulated the Vision❚ Substrate & many components available❚ Encourage continued commercialization of
the Vision❚ We all need to collectively demonstrate
cost efficiencies & benefits❚ End Users must embrace and buy into this
revolutionary development
